Popping back into this thread because I only now just noticed some of these sprites (the ones in particular dating back to August. Just goes to show how frequent I am on forums these days. :I). Anyway...

So you ended up making an Archeops sprite with the tail facing behind after all! Looks good, I'm glad I was at least able to give you the idea. The backsprite also looks nice, Archeops' head reminds me of a serpent somewhat.
